Summary:Potential effects of changes in future climatic conditions on the ground-water system. These changes probably would result in greater rates of precipitation and, consequently, greater rates of recharge. The study was performed by simulating the ground-water system using a two-dimensional, finite-element ground-water flow model. The simulated position of the water table rose as much as 130 meters near the primary repository area at Yucca Mountain for a simulation involving a 100-percent increase in precipitation compared to modern-day conditions. Despite the water-table rise, no flooding of the potential repository would occur at its current proposed location. According to the simulation, springs would discharge south and west of Timber Mountain; along Fortymile Canyon; in the Amargosa Desert near Lathrop Wells and Franklin Lake playa; and near Furnace Creek Ranch in Death Valley, where they presently discharge. Simulated directions of ground-water flow paths near the potential repository area generally would be the same for the baseline (modern-day climate) and the increased-recharge simulations, but the magnitude of Flow would increase by 2 to 4 times that of the baseline-simulation flux.—Modified author abstract.
